Title: Microwave stripline module in sandwich design for movement detectors
Inventor: KLIR VILEM
IPC: G01S7/03
Filed: 1981-02-24
Abstract: Microwave modules for movement detectors are primarily designed as cavity modules with a Gunn diode. This design is relatively bulky in the X-band (9.35 GHz), and the Gunn diode has a limited useful life and low efficiency (power consumption 80 to 150 mA). Furthermore, a number of movement detectors have been designed with a transistor oscillator in simple stripline technology. The disadvantage of this technology is that radiation losses occur at transition points in the microwave circuit which are higher than the permissible values in the FTZ regulations (3 x 10<-8> W). A module or the entire movement detector must therefore be additionally screened. These problems have been solved according to the invention by using a sandwich structure (layered circuit) for the first time (as far as is known) in the stripline module for movement detectors. The module comprises two plates (Fig. 1) which are glued together. The outsides are coated with an electrically conducting material, while the inside of one of the plates represents the microwave circuit (transistor oscillator, filter, transmission antenna and reception component). Possible uses include movement detectors (alarm devices), door openers and industrial applications. <IMAGE>
